Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of spore analyzers, and particularly relates to a spore analyzer. Background Technology
[0002] A spore analyzer is a specialized instrument used to detect, identify, and quantify spores (such as fungal spores, pollen, and bacterial spores) in air or liquid samples. It is widely used in agricultural disease early warning, environmental microbial monitoring, allergen research, and industrial cleanroom control. It captures target particles through efficient sampling (such as air extraction or liquid filtration) and uses microscopic imaging, molecular biology (such as PCR), or spectroscopic techniques (such as laser-induced fluorescence) to identify spore species, calculate concentrations, and assess activity. This helps users quickly grasp the dynamics of microbial contamination, providing data support for disease prevention and control, environmental health assessment, or production process optimization. Some high-end models also feature automated and intelligent functions, such as AI image recognition or real-time data transmission, further improving detection efficiency and accuracy.
[0003] In the use of existing technology, the filter cartridge will gradually form a filter cake layer on the surface of the filter material due to the interception of a large number of aerosol particles (including target spores and non-target impurities) during continuous operation. This will cause the porosity to decrease and the flow resistance to increase. This phenomenon directly causes the system's air intake flow rate to decrease over time, affecting the sampling efficiency and measurement accuracy, especially in long-term continuous monitoring or high-concentration particulate matter environments.
[0004] Based on this, the present invention designs a spore analyzer to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the problem that, during continuous operation, the filter cartridge traps a large number of aerosol particles (including target spores and non-target impurities), causing a filter cake layer to gradually form on the surface of the filter material, resulting in decreased porosity and increased flow resistance. This phenomenon directly leads to a decrease in the system's airflow rate over time, affecting sampling efficiency and measurement accuracy. Therefore, this invention proposes a spore analyzer.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A spore analyzer includes an analyzer body, four connecting posts fixedly connected to the upper surface of the analyzer body, a protective cover fixedly connected to the upper surface of the four connecting posts, a filter cartridge fixedly connected to the upper surface of the analyzer body, a cleaning device being provided outside the filter cartridge, and a blowing device fixedly connected inside the protective cover.
[0008] The cleaning device includes a collar, a scraper is fixedly connected to the upper surface of the collar, and a pusher plate is fixedly connected to one side of the collar.
[0009] As a further description of the above technical solution:
[0010] The cleaning device also includes four connecting rods, which are symmetrically installed outside the collar. One end of each connecting rod is fixedly connected to a sliding sleeve, which is sleeved outside the connecting post.
[0011] As a further description of the above technical solution:
[0012] The inner diameter of the scraper is slightly larger than the diameter of the filter cylinder cross-section, and the two are tightly fitted together.
[0013] As a further description of the above technical solution:
[0014] The inner diameter of the sliding sleeve is slightly larger than the cross-section of the connecting column, and a sliding connection is formed between the two.
[0015] As a further description of the above technical solution:
[0016] The push plate is L-shaped and has a hand-held slot inside. The push plate is attached to the upper surface of the analyzer body.
[0017] As a further description of the above technical solution:
[0018] The blowing device includes two fixed rods, which are fixedly connected inside the protective cover. The lower surfaces of the two fixed rods are fixedly connected to the same filter frame. The air collecting shell is fixedly connected below the filter frame. The upper surface of the filter frame is fixedly connected to a drive motor, and the output end of the drive motor is fixedly connected to a fan blade.
[0019] As a further description of the above technical solution:
[0020] The fan blades are disposed inside the air collecting shell, and the diameter of the fan blades is slightly smaller than the inner diameter of the air collecting shell.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0022] 1. In this utility model, the cleaning operation of the filter cartridge is achieved through the synergistic action of the hand-held groove and the push plate. When the operator places his hand in the hand-held groove and applies pushing force, the push plate drives the collar and scraper to move axially. The scraper maintains close contact with the outer surface of the filter cartridge and effectively peels off the particles accumulated on the surface during the relative movement. The specially designed inclined scraper structure can guide the peeled pollutants to the upper surface of the analyzer body to achieve directional removal, thereby maintaining the permeability of the filter cartridge.
[0023] 2. In this utility model, when the drive motor is started, the airflow generated by the rotation of the fan blades is rectified by the air collector shroud to form a directional airflow field. This airflow field has two functions: on the one hand, it enhances the cleaning effect of the contact surface between the scraper and the filter cartridge; on the other hand, it removes the peeling particles accumulated on the surface of the analyzer body for a second time. This cleaning method that combines mechanical scraping and airflow purging significantly improves the self-maintenance capability of the system. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-4 ,
[0032] First embodiment:
[0033] This utility model provides a technical solution: a spore analyzer, including an analyzer body 1, four connecting posts 2 fixedly connected to the upper surface of the analyzer body 1, a protective cover 3 fixedly connected to the upper surface of the four connecting posts 2, a filter cylinder 4 fixedly connected to the upper surface of the analyzer body 1, a cleaning device 5 being provided on the outer sleeve of the filter cylinder 4, and a blowing device 6 fixedly connected inside the protective cover 3.
[0034] The cleaning device 5 includes a collar 501, on the upper surface of which a scraper 506 is fixedly connected. A pusher plate 504 is fixedly connected to one side of the collar 501. The inner diameter of the scraper 506 is slightly larger than the outer diameter of the filter cartridge 4, forming a tight but non-rigid pressing fit. This design allows the scraper 506 to effectively scrape off particles attached to the surface of the filter cartridge 4 during movement, while avoiding frictional damage caused by interference fit. The inclined edge of the scraper 506 further optimizes the peeling and guiding effect of particles.
[0035] Specifically, such as Figures 2-3 As shown, the cleaning device 5 also includes four connecting rods 502, which are symmetrically installed outside the collar 501. One end of each connecting rod 502 is fixedly connected to a sliding sleeve 503, which is sleeved on the outside of the connecting post 2. The sliding sleeve 503 and the connecting post 2 adopt a clearance fit sliding connection design, which ensures the smooth axial movement of the collar 501 under the action of the push plate 504 and avoids jamming caused by excessive frictional resistance. The connecting post 2 provides precise guidance for the sliding sleeve 503, so that the scraper 506 always maintains a stable contact pressure with the outer surface of the filter cylinder 4, thereby ensuring the uniformity and consistency of the cleaning effect.
[0036] The inner diameter of the scraper 506 is slightly larger than the diameter of the cross-section of the filter cylinder 4, and the two fit tightly together. The inner diameter of the sliding sleeve 503 is slightly larger than the cross-section of the connecting column 2, and the two form a sliding connection. The push plate 504 is L-shaped and has a hand-held groove 505 inside. The push plate 504 overlaps the upper surface of the analyzer body 1.
[0037] During operation, the cleaning of the filter cartridge 4 is achieved through the coordinated action of the hand-held slot 505 and the push plate 504. When the operator places their hand in the hand-held slot 505 and applies a pushing force, the push plate 504 drives the collar 501 and the scraper 506 to move axially. The scraper 506 maintains close contact with the outer surface of the filter cartridge 4 and effectively strips off the particles accumulated on the surface during the relative movement. The specially designed inclined scraper 506 structure can guide the stripped pollutants to the upper surface of the analyzer body 1 to achieve directional removal, thereby maintaining the permeability of the filter cartridge 4.
[0038] Second embodiment:
[0039] Specifically, such as Figure 4As shown, the blowing device 6 includes two fixed rods 601, which are fixedly connected inside the protective cover 3. The lower surfaces of the two fixed rods 601 are fixedly connected to the same filter frame 602. The filter frame 602 is fixedly connected to the air collecting shell 603. The filter frame 602 serves as a pretreatment structure for the airflow channel, which can intercept large particles of impurities to prevent them from entering the air collecting shell 603. Its direct connection with the air collecting shell 603 forms a continuous airflow path, reducing pressure loss and maintaining airflow speed, thereby optimizing the purging effect.
[0040] A drive motor 604 is fixedly connected to the upper surface of the filter frame 602. A fan blade 605 is fixedly connected to the output end of the drive motor 604. The fan blade 605 is set inside the air collecting shell 603, and the diameter of the fan blade 605 is slightly smaller than the inner diameter of the air collecting shell 603.
[0041] During operation, when the drive motor 604 is started, the airflow generated by the rotation of the fan blade 605 is rectified by the air collector shroud to form a directional airflow field. This airflow field has two functions: on the one hand, it enhances the cleaning effect of the contact surface between the scraper 506 and the filter cartridge 4; on the other hand, it removes the peeling particles accumulated on the surface of the analyzer body 1. This cleaning method, which combines mechanical scraping and airflow purging, significantly improves the self-maintenance capability of the system.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
